Is there any reason that I cannot user PC 3200 DDR in a board that supports 2700 (without the speed benifit of the 3200 of course) my thinking is that if i get a used board or cheaper board for now and want to replace it down the road with the SP I dont want to have to rebuy the ram as well.

Occasionally some boards not rated for faster speed have issues, but most of the time faster ram should be OK. I think others have used faster ram on VIA mobos without trouble. I'm sure those that have will post.
